    4 MHz, 6A Integrated Switch
    Synchronous Buck Regulator General Description Features The Micrel MIC22601 is a high efficiency 6A Integrated
    switch synchronous buck (step-down) regulator. The
    MIC22601 is optimized for highest efficiency (greater than
    90%), while still switching at 4MHz over a broad load
    range with only 0.22ВµH inductor and down to 22ВµF output
    capacitor. The ultra-high speed control loop keeps the
    output voltage within regulation even under extreme
    transient load swings commonly found in FPGAs and low
    voltage ASICs. The output voltage can be adjusted down
    to 0.7V to address all low voltage power needs. A full
    range of sequencing and tracking options is available with
    the MIC22601. The enable/delay pin, combined with the
    power good PG/POR pin, allows multiple outputs to be
    sequenced in any way during turn on and turn off. The RC
    (Ramp Controlв„ў) pin allows the device to be connected to
    another product in the MIC22xxx and/or MIC68xxx family,
    to keep the output voltages within a certain О”V on start up.
    The MIC22601 is available in a 24-pin 4mm x 4mm MLFВ®
    package with a junction operating temperature range from
    –40°C to +125°C.
